7 Ordering Information Factored Resistance Strength (ØN n And ØV n) Calculated In Accordance With ACI 8 Appendix D: - Tabular values are provided for illustration and are applicable for single anchors installed in normalweight concrete with minimum slab thickness, ha = hmin, and with the following conditions: - ca is greater than or equal to the critical edge distance, cac (table values based on ca = cac). - ca2 is greater than or equal to.5 times ca. 2- Calculations were performed according to ACI 8- Appendix D. The load level corresponding to the controlling failure mode is listed. (e.g. For tension: steel, concrete breakout and pullout; For shear: steel, concrete breakout and pryout). Furthermore, the capacities for concrete breakout strength in tension Ca and pryout strength in shear are calculated using the effective embedment values, hef, for the selected anchors as noted in the design information tables. Please also reference the installation specifications for more information. Ca2 - Strength reduction factors (ø) were based on ACI 8 Section 9.2 for load combinations. Condition B is assumed. 4- Tabular values are permitted for static loads only, seismic loading is not considered with these tables. 5- For designs that include combined tension and shear, the interaction of tension and shear loads must be calculated in accordance with ACI 8 Appendix D. 6- Interpolation is not permitted to be used with the tabular values.
